The lateral attitude, left and right of workpiece is changed determining, it is simple to be adjusted the punch position of workpiece；
Concrete, longitudinal base 4 and pedestal 3 drive connection, transverse base 5 and longitudinal base 4 drive connection, both is driven
It is dynamically connected and is the connection using step actuator 18 to carry out, thus realize longitudinal base 4 opposite base 3 and make longitudinally adjusted shifting
Dynamic, transverse base 5 laterally adjusts relative to longitudinal base 4 and moves；
Being installed with several clamping devices in transverse base 5, as depicted in figs. 1 and 2, clamping device includes being located at the horizontal end
Grip slipper 6 on seat 5, grip slipper 6 is supporting role, and grip slipper 6 is provided with vertical depression bar seat 7, and depression bar seat 7 upper articulation sets
Having clamping depression bar 8, the middle part of clamping depression bar 8 is hinged with depression bar seat 7, and clamping depression bar 8 forms the lever knot with depression bar seat 7 as fulcrum
Structure；Specifically, depression bar seat 7 is spill seat, clamping depression bar 8 is hinged with spill seat in embedding spill seat.
Clamping depression bar 8 two parts before and after depression bar seat 7, not for clamping part 9 and top splenium 10, in order to improve clamping fastness, are pressed
Pole socket 7 near clamping part 9 to improve leverage effects；It is respectively arranged below with clamping group in clamping part 9 and top splenium 10 on grip slipper 6
Part 11 and top air cylinder 12, top air cylinder 12 improves power upwards to raise the top splenium 10 of clamping depression bar 8, thus promotes clamping
Workpiece is clamped by portion 9；Top splenium 10 with top air cylinder 12 hinged, it is simple to adjust push up air cylinder 12 in lifting process with folder
Hold the angle of depression bar 8.
Clamp assemblies 11 includes casting die 13 and support member 14, and clamping part 9 is connected with upper casting die 13 top, concrete, folder
Hold portion 9 and upper casting die 13 top to be connected to one structure, or at the top of upper casting die 13, articulated elements is set, by clamping part
9 is hinged with upper casting die 13 top, and the bottom of upper casting die 13 and the top of support member 14 are provided with the folder for clamping workpiece matched
Hold groove 15；Organisation of working 2 includes the processing drill 17 processed seat 16 and be located on processing seat 16, holding tank 15 perforate direction with add
